I hear time and again from this side of the House people talking about giving more to the primary care networks. As a GP, I worry that this could be a concern for my public health colleagues as well because they already serve a function—of non-covid health service. I would be interested to hear the thoughts of others on this concern: what happens if we keep putting more pressure on public health and GPs, who are already dealing with non-covid stuff? How do we deal with this? It makes a lot of sense to bring in a national service to try to do that; we did that with the Army to help with test, track and trace. What does the hon. Lady think about the possibility of extra pressure there?
